Scanner - can't connect wireless printer

In the past always printed to my Epson XP-400 and currently can even print some information from software, but can't print any pictures that I have scanned. Receiving error message " cannot print because printer supported by this software is not installed." And when I look there is no printer showing up in the print section in my image garden either. Recently had a new power supply installed could this have screwed something up? Do I need to reload the software, and if so are there any precautions. Thank you.

Welcome to the Canon Forums, and thanks for your inquiry! Canon does not manufacture this printer model, so we would not be able to assist with this issue. You may want to check out Epson's website at http://www.epson.com for further assistance.
